After World War 3 all that is left of the destroyed planet is two continents. In the north - a mutated strain of American and Russian males, forming the USSSR, in the south - all that is left of womankind, renamed Vaginia. The two armies are soon at odds with each other. The men perfect their most destructive weapon yet (shaped like a penis) called the 'Big One', while the women build 'Big Mama', a superbomb (shaped like a breast), together capable of destroying the solar system in a cosmic super orgasm. Fred, a retired superhero (now working as a garbageman) is given the task of keeping the peace. He spectacularly fails by falling in love with the USSSR's Commander's young mistress, Liberty. She disappears after Fred is seduced by Una leader of the Vaginians. In an effort to be reunited with Liberty, Fred inadvertently starts the Fourth World War. Can Fred and Liberty survive the impending cosmic orgasm?
